Karen and Tim were closer than ever since their last encounter a few days ago. It was all they could do not to touch each other intimately in front of their parents, nor did they have any opportunities to be alone together since their very sexy tryst.

Well, a Saturday soon came along when their parents announced one morning at breakfast that they were going into town, about 50 miles away, for the day and night.

They asked Karen and Tim if they would mind being alone while they were gone. Tim said he didn't mind because he had a new video game he wanted to try and he could really get absorbed for hours once he started that. He was a good cook so he would fix his own lunch and dinner. He said he probably wouldn't even notice they were gone!

Karen said she would get together with some friends. They would all go shopping, have lunch, go see a movie, and have dinner together. She said she would stay over with one of them and would be home in the morning.

Their parents were then assured the kids would be fine. Their Mom said they would be home around noon on Sunday. They went upstairs, picked up their overnight bags, came down, and left.

Karen and Tim were immediately excited at the prospect of having a whole day and night together! Karen said, "Let's not go crazy! Why don't we go on a picnic?"

Their home was in a rural area and they lived on 40 acres that had a small lake in the center of it about 5 acres from the house. They were lucky because it was a beautiful warm, sunny day.

Tim said, "Yeah, that sounds like fun! Let's go down to the lake with a picnic lunch. We can swim and lay out in the sun!" Karen agreed so they both went upstairs to get ready.

Karen went to her room and slipped into her tiny, silky bikini. The material felt so good against her skin and her nipples got hard immediately against the top. She also felt a dampness between her legs when she put on the silky panty just thinking about being alone with Tim for the day and night. She gathered her wandering thoughts and threw on a tank and shorts with her sandals. She ran downstairs to meet up with Tim.

Meanwhile, Tim was in his room, grabbing his swim shorts, pulling them up over his semi-hard erection at the thought of what might happen with Karen while their parents were away. He adjusted himself quickly and threw on a t-shirt and some sandals. He told himself to get a grip and calm down, to just wait and see! He left his room and went downstairs to join Karen.

Once they met up in the kitchen, they made some sandwiches and snacks. They got a cooler and included a 12-pack of beer they didn't think their parents would miss. They grabbed the cooler, a couple of towels, and a blanket, and left, making their way down the path to the lake.

After they got there, they laid out the blanket in a sunny spot and anchored it down with rocks. They decided to strip out of their shorts and tops, and they each had a beer while laying on the blanket in their swim suits.

Tim noticed how small Karen's bikini was and how her nipples perked up from her firm rounded breasts through her top. It made his cock rise in his swim shorts and he had to squirm a little so it wasn't obvious to Karen. He didn't want to be forward while they were just talking at this point.

Karen couldn't help but notice that Tim was eyeing her nipples and breasts. She also saw the bulge in his swim shorts. It made for more dampness in her bikini panty. She was getting turned on thinking about his cock.

It started to get warm in the sun as each of them finished their beer. They decided to have one more. They talked about mutual friends and the coming school year at college, safe topics, each avoiding their mutual attraction, but each of them was getting turned on.

Once they finished their second beer, they were getting very warm in the bright sunshine. Karen suggested they go swimming. Tim instantly agreed and suggested that they should go in naked!

Karen acted shocked at first, but she got further turned on at the thought and readily agreed. They quickly stripped down.

Tim's cock was semi-hard and Karen's nipples were sticking straight out from her breasts. It was clear they were both turned on at seeing each other naked again.

They walked into the water and swam out until it was up to their necks. They were playful at first and started splashing each other, but

soon they were next to each other.

Karen reached out and touched Tim's cock. By now, he was fully erect. She began to stroke his big hard cock. He smiled and looked at her lovingly.

Tim reached out and felt Karen's firm breasts. He pinched and pulled her nipples. She pushed herself against his hands and let out a small moan.

They decided to get out of the water and go back to their blanket to continue their explorations of each other on the beach. Once there, Karen continued to stroke Tim's cock while Tim moved his hand down between Karen's legs.

Tim had pre-cum on the tip of his cock and Karen used it to slide easily and faster over his cock. He moaned deep in his throat. By this time, he put his finger in her pussy and was plunging it in and out of her.

He could tell she was enjoying what he was doing because she was getting very wet. He felt for her clit with his thumb. It was hard and sticking out of its hood.

She was pushing against his hand. He was thrusting his cock up into her fist, getting more turned on by the second. It was clear they were both close to cumming.

Tim gave one final rub on Karen's clit and she exploded into a huge orgasm. She was humping his hand, squeezing her legs together and writhing beneath his onslaught. She finally opened her legs and pulled away, unable to take anymore as she became so sensitive to his touch.

When Karen came, Tim couldn't take anymore and he let go with his orgasm. He came with such a force that he exploded with long ropes of cum over Karen's hand onto his chest and stomach. He even shot cum onto his chin!

They both lay back, completely sated. They looked over at each other and gave each other huge smiles! They were both just glowing and held each other close.

Shortly they got up and ran into the lake to rinse off. Karen rubbed the cum off the front of Tim's body and his cock. Tim rubbed Karen's breasts and between her legs to rinse her off. They fondled each other a little bit more and hugged fiercely.

They soon decided they were getting cold, and that they were thirsty and starving. They got out of the lake and ran back to the blanket.

They enjoyed the next few minutes fondling each other while they slathered sunscreen on each other's bodies. They didn't want to get fried in the warm sunshine.

They each had another beer along with their sandwiches. They talked about how much they enjoyed touching each other and how much they turned each other on.

They agreed that they did not feel they were doing anything wrong. Karen told Tim how much she loved him. Tim told her that he loved her, too. They had always been close as sister and brother, looking out for each other all through their lives. This just seemed like a natural progression of that affection.

After lunch, they had another beer and continued talking. They talked about how much they loved each other's bodies. Tim said he had always admired Karen's figure and had peeked at her running across the hall from her room in a towel to the bathroom a few times. Karen said she had always wondered if Tim had a big cock and she said she was thrilled to know that he did!

Soon, after all the beers, swimming, talking, and sex, they became sleepy. They laid down on the blanket, arms and legs entwined, and fell sound asleep.

When they woke up awhile later, still entwined around each other, it had cooled off and the sun was low in the sky. They unwrapped themselves from each other and figured they better get back to the house before sunset.

They got dressed, collected their stuff, and headed back to the house. Once there, they stripped off their clothes, threw them, along with the towels and blanket, into the washer, started it and, naked, went to take a shower.

They soaped each other up and fondled each other all over. They got turned on and made glorious love again. They each reached explosive orgasms and collapsed on the shower floor. They let the shower water flow over them to revive them.

Once they were refreshed and clean, they got out, dried each other off, and then decided to stay naked for the evening. This was something they could not normally do, so they wanted to enjoy it while they could. They headed down to the kitchen to have dinner.

Once there, Tim said he would make them omelettes for dinner. Karen said that sounded good to her and watched him from a stool pulled up to the kitchen counter.

Karen's breasts showed just over the edge of the counter. Tim kept looking over at them hungrily, wanting to pinch and pull her nipples the way she liked. His cock was semi-hard and Karen kept staring at it, imagining taking it into her mouth and sucking it. They each had a beer while he fixed dinner.

Once they had dinner, they cleaned everything up, and went into the family room to watch a movie. They brought another beer and decided on a rom-com that didn't really hold their interest.

They just sat through it to pass the time until bedtime. There was sexual tension in the air the entire evening. The suspense of what the night may bring kept them both in a state of semi-arousal.

Once the movie was finally over, they went upstairs to go to bed. Karen said, "Are we going to sleep together?" Tim said, "Yeah. Of course, aren't we?" Karen quickly answered, "Oh, yes!" Karen had the bigger bed so they decided to sleep in her room.

Once there, Karen slipped into bed and pulled the sheet over herself. Tim followed close behind. He, too, pulled the sheet over himself and snuggled in next to Karen. It was a little cool in the room, but they were both feeling very hot!

Tim was still semi-hard and Karen's nipples were hard and her pussy was wet. They reached for each other at the same time. They began to kiss, at first gently, but growing more passionate as they continued.

Tim reached out for Karen's breasts and fondled her nipples. She pushed them into his hands wanting his touch. She was kissing his neck as he began to suck and nibble on her nipples. She asked him to please gently bite them which he did. She moaned as he bit them.

She reached down and felt his cock which was fully hard by this time. She began to stroke him up and down. She reached down and gently fondled his balls. He seemed to like this as he sucked in a deep breath when she did this.

She returned to stroking his cock. He had pre-cum on the tip which she rubbed up and down his big hard cock.

By this time, he had moved his hand down to her pussy. He felt how wet she was and inserted a finger inside. He followed that with another and continued to finger fuck her fast and hard. It felt wonderful!

She decided to turn around and take his cock into her mouth. He was so huge she couldn't take all of him in her mouth. She stroked what she couldn't fit and he gave out a low moan deep in his throat. She started to suck his cock up and down while she stroked him with the same motion.

Tim also moved around and took Karen's pussy in his mouth. She was so wet and he started to lick inside her pussy. He flicked in and out faster and faster. Karen was moaning with his attentions to her pussy.

They were both very turned on. Suddenly, Tim stopped what he was doing and pulled away from Karen's pussy. He turned up to kiss her. She tasted her juices on his lips and tongue. This turned them both on even more!

Tim pulled back and looked up at Karen questioningly. He said, "Karen, you know I love you, right?" Karen hesitantly said, "Yes, and I love you, Tim." Tim said, "Well, can we take this to the next level?" Karen said, "Tim, what do you mean?" Tim said, "Karen, I really want to fuck you!"

Karen looked a little shocked but soon recovered. She said, "Tim, I have to admit, I've been thinking about the same thing, but I'm scared. What if something happens?"

Tim said, "I don't care. All I know is that I love you and I want to be with you this way. I want to make love to you fully. We will always be together no matter what happens. Let's do this special thing."

Karen looked into Tim's loving eyes and finally said, "Yes, Tim. I love you so much. I want this, too. Please! Let's fuck - now! I'm so ready for you!"

With that, Karen laid back and Tim moved over her. They kissed lovingly and with longing. He fondled her breasts and nipples. Karen reached down and stroked Tim's cock. It was so big and rock hard.

They were both moaning with desire. Tim moved then and rubbed his cock between Karen's legs and against her clit. He did this a few times until she begged him to please fuck her.

He obliged and rubbed his cock along her pussy lips and then plunged his cock into her very wet pussy. They both let out moans of pleasure. Tim lifted Karen's legs over his shoulders so he could go even deeper into Karen's pussy.

Tim fully entered Karen's pussy. She was so tight that they both felt every movement of Tim's cock inside her.

They developed a rhythm and seemed to fit each other as if they were just meant to be together. They started to move faster as Tim plunged into Karen harder and deeper.

They were both close to their climax. Then, Karen fondled her nipples while Tim watched. This was more than they could take and they both suddenly exploded into fierce orgasms, moaning out loud.

Tim kept shooting load after load of cum into Karen's pussy. Karen kept writhing under Tim as she felt him rubbing against her clit. She kept cumming and cumming.

Tim's cock eventually softened and he rolled over and off Karen. She moved over close to his side as he put his arm around her. They slowly recovered their breathing and kissed gently. They covered up with the sheet and were soon fast asleep.

During the night, they both awoke and had to use the bathroom. They came back and made love again, this time slowly and gently, savoring every moment. They both came with the same force as before. They were well and truly now connected as lovers.

In the morning, they made passionate love again and then shared a shower. They soaped each other up and washed each other's bodies. Of course, they both became very turned on once again.

Tim turned Karen around and pushed his cock between her legs. She leaned over for him to enter her from behind and he plunged his cock into her pussy. They fucked this way under the flow of the shower. It felt wonderful for both of them. It didn't take long before they were both cumming against each other. They rinsed off, got out and dried each other off playfully.

By this time, they were starving from all their "exercise" so they ran down to the kitchen to have some breakfast. They stayed naked just because they could!

They decided on cereal because it was the easiest. They each also had some juice and brought a cup of coffee into the family room.

They talked about what they were going to do until their parents got home. Karen said, "I have an idea." Tim said, "What's that?" Karen said, "Do you have any porn we could watch? Any with girls making love to each other?"

Tim was surprised at her request but quickly recovered. He thought for a minute and then said, "Yes. I think I have just what you're looking for. Be right back."

He went up to his room and quickly returned. He put a disc in the disc player and started it up. Soon the film started and it showed a number of characters including three women and one man.

Before long in the film, the three women were fondling and licking each other. Karen was transfixed.

She had never seen women making love to each other so she easily became turned on. She reached out and touched her nipples which were standing out straight from her breasts. She continued to watch the film, mesmerized.

Tim was getting turned on, too, both by the film and by watching Karen getting turned on. As the film continued, he mostly watched Karen getting more turned on by the minute. He couldn't help but fondle himself as he watched her getting more turned on by the minute.

Karen was getting more and more turned on. She touched herself between her legs and felt how wet she was. The movie was getting hotter and hotter, but she wanted to be with Tim now.

She looked over at him and saw that he was watching her. His cock was hard and standing up proudly from his body and he kept touching himself. Well, this was all Karen needed.

She leaned over and took him in her mouth. She sucked him up and down while stroking him. He groaned. He reached down and fingered her pussy using his thumb to rub her clit.

They pulled away from each other and Karen moved around to sit on Tim's lap. She was very wet by now. She easily slid Tim's cock inside herself and proceeded to ride him up and down.

She set the rhythm. Tim put his hands on her rump and lifted her up and down, helping her ride his cock. They were in a hurry this time because they were both so hot from the film. Karen was moving fast and hard, riding Tim's cock furiously.

Very soon, they were both cumming. Tim emptied his cock into Karen's pussy, pulsing time after time. She could feel his cock throbbing inside her and she squeezed down on it while she came with wild abandon.

They slowly recovered and Tim's softened cock slipped out of Karen's soaked pussy. She was quivering and shaking and had to stand up to stretch her legs.

Tim's cum leaked out of Karen's pussy mixed with her juices. It was running down her legs. It felt so good.

They decided to go and take another quick shower as it was getting late in the morning. They again soaped each other up and washed each other. It just felt so good to touch one another.

Karen turned around and, with her back to Tim, she leaned back against him, pinning his semi-erect cock between her ass cheeks. She cried out, "Please, Tim!"

That's all Tim needed to hear and he was instantly hard against her. Karen leaned forward and spread her legs for him. Tim easily entered her already-wet pussy from behind and began to fuck her furiously.

They both wanted it rough and fast and hard. They didn't know when they would have the chance to be together like this again so they were desperate in their final lovemaking.

They came quickly and fell against each other, spent. The shower continued to rain down on them. They quickly washed each other, rinsed, got out and dried each other off, then went to get dressed.

They got dressed and went downstairs. They were in the family room watching trivial TV just as their parents came in the door, glowing from their time away.

Their parents asked them how things went while they were gone. Karen and Tim shared a secret smile before Karen replied, "Oh, we were just fine, Mom and Dad. You can go out of town anytime!" Tim said, "Yeah, everything went OK!"

The two of them just grinned at each other, both knowing just how fine and OK it had been!
